A BTP spokesman said: "The charges relate to an incident where a man was on top of railway infrastructure, resulting in a number of rail services from St Pancras International needing to be suspended as a safety precaution."

He was remanded in custody to appear before Westminster Magistrates' Court on Monday.

Assistant Chief Constable Sean O'Callaghan said: "Friday evening's incident was extremely challenging and I would like to thank the public for their patience whilst a number of specialist teams responded.

"This was a fast-paced inquiry and I am pleased that a man has now been charged in connection."

Several services on the route had to be scrapped following the incident, which began on Friday evening and ended when a suspect was arrested around 12 hours later.

The incident happened on the day the UK was originally due to leave the EU, and followed a day of Brexit protests in Westminster.
